Cardiac Conduction System
Educational only: videos on MedicalVideos.com are for general information and are not medical advice. Always consult your own doctor about your health.
The normal electrical conduction in the heart allows the impulse that is generated by the sinoatrial node (SA node) of the heart to be propagated to (and stimulate) the cardiac muscle (myocardium). The myocardium contracts after stimulation.
This video in 30 seconds
This video explains the cardiac conduction system. It describes how the electrical impulse generated by the sinoatrial node is propagated to the cardiac muscle, and how the myocardium contracts after stimulation.
Key points
- Explains electrical conduction in the heart
- Describes the sinoatrial node as the impulse generator
- Covers propagation of the impulse to the myocardium and contraction
Video Overview
This video presents “Cardiac Conduction System” — The normal electrical conduction in the heart allows the impulse that is generated by the sinoatrial node (SA node) of the heart to be propagated to (and stimulate) the cardiac muscle (myocardium). The myocardium contracts after. Whether you are preparing for a procedure, studying the technique, or learning how a condition is assessed, the recording shows the process as it is performed in practice.
